6×6 South Australia
6×6 can legally carry and tow substantially more weight than the comparable 4×4, with a significant increase in traction, mobility and safety. 6×6 Conversions are available for 70 & 200 Series Toyota Landcruiser, Hilux, Y61 Patrol, Ranger, BT50, NP300 and other models.
6×6 Conversion is best suited to applications where off-road mobility with substantial weight, high speed highway point to point travel is required.

How it Works?
This design includes a pair of driven axles that are connected by Suspension and Driveline.
6×6 Suspension
The core of the 6×6 design is the pivoting 50:50 load share beam, pivoting centrally from the chassis between the 2 rear wheels, supported by coil springs (or airbags) in each of the 4 corners. Upper ‘A’ arms and ball joint pivot allow movement from front to rear, but also side to side, providing massive articulation, allowing each axle to walk over an obstacle while the others remain on the ground, increasing stability and traction.
- The coil option has 400mm articulation, air bags allow upto 550mm.
- The axles are held in position front to rear with 4 control arms.
- There are no sideways mounting panhard rods, the upper ’A’ arms provide sideways positioning.
- There are no axle straps limiting axle movement/articulation.
Another benefit of this design is that cornering is enhanced, providing exceptional on-road stability, manoeuvrability and less axle scrub than other systems.
This is achieved by a ‘bogie axle roll steer’.
As you enter into corners, the compression and extension of the coil springs force the front-rear control arms to move – and each moves in an arc, providing a rear wheel steer component.
For example, turning left:
Rearmost axle
As you enter into the corner, the lean of the vehicle compresses the coil on the RHS, the axle moves slightly rearward as the arm swings upward to horizontal, while the LHS moves slightly forward as the control arm pivots downward, as the LHS coil expands.
The opposite is happening with the forward axle, the RHS wheel moves forward, the LHS moves rearward.
The net result being the 2 axles are assisting in steer, rather than opposing each other as in other 6×6 or lazy axle systems. This increases loaded and unloaded stability immensely.
Ride Quality
The suspension design provides great all-road ride quality with even more supple absorption of bumps as the load increases. However, ride quality is high, even with as little as 10% of the GVM.
Ride Height
The suspension will drop 65mm to be level front to rear at GVM.
6×6 Driveline
There is only one tail-shaft from the transfer case driving the rear axles. (no vibrating second shaft from a transfer case PTO).
The shaft drives the first differential, through a patented combination ‘drive-through differential and power divider’, which is coupled to a jack shaft providing power to the rearmost differential.
The forward differential is a custom build, using Ford 9.5” or 10” high quality gear sets, with 35mm splined pinion flange and 31 spline axle flanges, mounted into a custom manufactured housing. This differential also uses an ARB Air Locker.
The rearmost differential is the original in a custom housing.
Both axles are ‘in-track’ with the front.
Maintenance
There is minimal extra maintenance required with general use. The most important item is to replace the drive-through differential oil as often as the engine oil. Otherwise maintenance will be commensurate with use of the vehicle.
Summary
The end result is a highway friendly high capacity vehicle with outstanding off-road capability while carrying substantial loads, comfortable on all road surfaces at all loads, with minimal extra maintenance and fuel consumption, fully compliant at all GVM/GCM combinations.

Customer Reviews
Just thought I’d send you a note post the remapping of my Hilux. In short it’s fantastic. Completely different vehicle. Easy to drive, quick, plenty of go and pulls like a mule. Don’t need to push the power button any more. Job well done. Appreciate your advice. Just filled up the Hilux. 629kms put in 56.88ltrs. Happy with that!!
Great shop. Went in for parts for my new Ute. They did everything they could to help and recommend the best parts and best advice. Would highly recommend. They run a tight ship!
Just had a major service on the 100 series. Very reasonable prices. Great service and information. Will definitely be coming back.
GO4X4 Team helped diagnose a fault I had with a dodgy sensor and advised a better option. Absolutely stoked with how the cruiser runs now. She’s an absolutely different car to drive! GO4X4 also let me have a spin of their auto 79 around the block and words cannot describe that thing. It is an experience that needs to be enjoyed by all! Cheers guys!
